I think my advice would be to sell between 1/3 to 1/4 to replace the FIAT taken from savings.

While his would be at a loss, the woman complaining in the reddit post clearly sees it as a very speculative investment (at best). You would then negotiate an allowance to do "dollar cost averaging".

Oh and try to diversify your interests a bit. People tire of hearing about Bitcoin. (Ask me how I know.)
